I am in the process of undertaking a DIYPNP project for my 1991 MX5. This new kit is based on the Megasquirt II design and won’t work with the existing Megasquirt I baseline maps.
I may try to use the 1.8L MX5 DIYPNP maps but I plan to double check these settings against the known base settings for the 1990-1993 B6 engine.

After the disappointment I received when Vista completely bombed on my aged but still functional Dell Inspiron 4100 (Pentium IIIm 1Ghz) I thought it had been pushed to the corner and I was only using it for testing new Linux distributions. Even that has recently become a chore as Gnome has become slick and fancy.
I am lending my old Dell to a computerless friend who is currently in need, and Linux was a bit daunting for them. I thought I’d try Windows 7 32bit as it seems to run just fine on my Intel Atom machine.
To be brief I’m stunned with the performance. A near flawless install (except for a XP networking driver I pulled from the Dell site). Sure it’s not the full aero experience but none-the-less a hugely impressive performance for a machine that is around 8 years old!
Whilst browsing through the Direct2Dell blog I saw that Microsoft has announced the release date for Windows 7.
This has been confirmed as a tweet from the Microsoft team and on their blog.
At work I seem to be getting a reputation of being a ‘Mac guy’ because I have decent OsX knowledge but in reality I like to have a go at all the current operating systems and I certainly like to explore technology.
I have had the Windows 7 RC1 running on a home machine for a while now and I am considering installing it on a netbook as I’ve heard it works quite well with the Atom processor.
Windows 7 already seems fairly polished with only the occasional driver issue presenting itself. Microsoft have managed to get 7 in better shape than Vista in a fairly short timeframe and I think this will be a successful launch for them despite the economic conditions.
If you haven’t already tried Windows 7 I recommend downloading it and giving it a chance.
Many years ago I would eagerly await the weekend to go for a dirtbike ride in the State forests around Coffs Harbour with my brother and friends. Thinking back we would often discuss the future and what we would be riding when petrol became scarce and new technologies had become available.
We had decided that electric motorcycles would be the future but thought it would be odd being propelled through the forest on a quietly humming steed.
That was going on ten years ago now, I haven’t had my TT600R for going on eight years now and I don’t even live in Coffs Harbour anymore. I happened across a youtube video of an Electric motorcross bike in use (ignore the hooliganism) and looking carefully at the video I saw a website address across the bike Quantya.com. Apparently our dream of the future is a reality and you can buy electric motorcross (and road registerable) motorbikes across the world – just not in Australia.
It seems like such an excellent idea to me and I can’t wait to see what electric vehicles the world has to offer in the near future.
I’ll finish up with a promotional video for the Quantya.

Hewlett Packard seems to have updated their HP Mini note to the new model HP Mini 1000.
Whilst the HP Mininote seemed to get rave reviews for an excellent typing keyboard and build quality, concerns were raised over the performance of the VIA processor that was apparently inferior to the Atom.
In the web advertisement that leapt up in front of me earlier it appears that this product has been revised with the new model using the Intel Atom 1.6 like it’s obvious competitor the MSI Wind. This new model also has the option of a 10″ screen in addition to the existing 8.9″ so with interest I was wondering if this machine would muscle out the MSI Wind with similar specs to match the formidable typing ability.
Unfortunately I can see a chink in the armour of this new machine even before reading further. Having access only to a smaller SSD drive or a 4200RPM hard drive it becomes obvious that the machine must be using the 1.8″ ipod-style drive as opposed to the 2.5″ standard laptop drive used in the Wind.
Obviously there is probably a battery performance reasoning behind using the smaller drive plus it would make heat and internal packaging much easier for the designers it does greatly limit opportunities for I/O performance and storage upgrading. Currently it’s not hard to put a 7200rpm drive in a Wind or even a 500GB 5400rpm drive if storage space is more important than speed.
I will be attempting to get my hands on a review Mini 1000 so I can do a side by side comparison vs the Wind and I will compare it to other similar models such as the Apple Macbook Air and Dell mini 9.
This is an increasingly full and competitive corner of the computer market. How far off are we from reaching full market saturation, or will people keep purchasing ever new models because of the low entry price?
I’ve been toying with the idea of writing some iPhone apps. I’ve downloaded the SDK and played around a bit but I haven’t really created anything all that interesting. I was browsing a friends blog earlier tonight and I saw that he had helped another friend with some artwork for their iPhone project. I must say I’m very proud that they got their iPhone development off the ground and that it has been a success on the iTunes app store. My best wishes for a successful future writing for the iPhone and I hope I get cracking on it soon.
It could just be the circle of people I hang out in, but I have been absolutely stunned at the number of people I know who have an iPhone already. For a device that was released not all that long ago it’s a pretty amazing saturation.
There was quite a deal of excitement around my workplace as the discovery went out that google had released street view for most of australia.
Like many people I’m sure, I quickly looked up my house but was suprised to see someone elses car in my driveway. Either their photo footage is quite old or someone with a blue stationwagon was loading up my possessions while I was at work.
It is interesting that with all the places that can be viewed peope almost always first check the place they are most familiar with. It may be a case of “hey I can see my house from here!”

I wanted to try out the iphone wordpress blogging program but unfortunately it required a newer version of wordpress so I had to upgrade. Might as well take it up to 2.6!
I attended the Brisbane cocoa heads gathering tonight. I as late and unfortunately missed half of the presentations but saw that there was some knowledge to be gained from the group so I’ll be back next month. Hopefully with an app of my own to discuss.
Iphone battery always seems to be either flat or going flat.

I fell asleep on the lounge again last night which is starting to become a habit for me. I was awoken around 4am by my UPS beeping at me from the other side of the room.
At this time I noticed that the front curtains on the house were flashing like someone was flicking their headlights on and off at the front of my house so I peeked through the curtains and was suprised to see a HUGE shower of sparks coming from the powerpole out the front! It was making a crackle boom bang crackle kind of noise with an impressive shower of white/blue sparks about once per second.
Fearing a fallen power line and the fact it was 4am and raining I didn’t end up going outside but I switched off all my appliances at the wall and then watched it out the window for a few minutes until it stopped and I went to bed. I’m about to leave for work and I guess I’ll have a look up at the powerline and see if I can work out was making the lines short out. My verandah has an overhang that prevented me from seeing directly what was happening, I could just see the power wires leading up to it and a shower of sparks falling.
Well it’s finally all working.
The DSL was took about 30 seconds to setup but I spent about 4 hours working on my Linksys VOIP box before I had all the functionality available to me. I’m pleasantly surprised though to find the calls over VOIP are crystal clear and reliable. Surprisingly the voice quality appears better than PSTN.
I plan to write up a quick guide to iinet VOIP with my Linksys VOIP box soon.
